It depends on the ambient temperature and the setting of the thermostat.
an electric furnace runs off of 208/230 Volts while a typical gas furnace runs off of 120 also a gas furnace will have a valve for the gas relay where the gas enters the furnace.
The duration of Furnace - film - is 1.5 hours.
a furnace
Nozzle size fitted to the burner in GPH X 24 hours. Nozzle will be stamped with gallons per hour rating at 100 psi nominal pressure, and will also include the number of degrees the spray pattern is designed for. A .85 80 degree nozzle would use .85 X 24 = 20.4 gal of oil/ day if the pump is set at 100 psi delivery pressure. lc WRONG. What your saying is that a home will use 20.4 gallons a day. That means it would take approx 612 gallons of oil a month to heat the house. The right answer is this. Every hour that the furnace runs it will use .85 gallons. During the day the furnace comes on and shuts off many times. You would have to sit there with a stop watch and see how many hours it runs during the day. Most furnaces will come on for 5 to 10 minutes at a time. So if your furnace came on 15 times in 24 hours for 10 minutes each time would mean your furnace ran for 2.5 hours in 24 hours which would mean your furnace used 2.5 x .85 = 2.94 gallons rounded off with be 3 gallons a day. Most houses around 1000/15000 square will use between 2.5 and 4.5 gallons a day depending on how cold it gets. 4 gallons a day times 30 days would come out to 120 gallons a month. My house is 1200 square feet and we use around 100 gallons of fuel a month.
A furnace should cycle on and off after every 4 hours.
have baseboard heat boiler runs off furnace want to shut off furnace to save oil will it hurt anything
Generally allow one day for replacing a furnace and one day for replacing an air conditioner. You need to replace furnace and air conditioner at the same time.
A blast furnace runs continuously, and input materials are continually dumped in at the top to make their way down through the furnace. Shutting down a blast furnace for relining or other work is a major event in its life.
A resistance furnace runs on electricity so it will be some type of electrical transformer.

The furnace that is working properly should cycle on and off after every 3 - 4 hours.
